I am thinking of building a 9MM AR with a 5 inch 3 lug barrel. Does anyone know what I have to do to register the lower SBR, do i have to mark the lower etc. Thank in advance for an help
If you're not going the trust route, I believe you need the lower engraved with full name, city and state. It's been recommended to have this done first so that if it doesn't turn out, you haven't just ruined an NFA item, just a regular gun.
Yes form 1 and everything above along with 'certification form' everything in duplicate with the exception of the $200. I would suggest you not have the 5" barrel around until you receive the approved form 1 back.
